Husqvarna T540ixp review 

Used error obviously

That sucks!!! The case is only $60 or so. I think it’s a pretty easy fix

@@therealzigzagman the sprocket thing came off, now it makes a spooky buzzing sound

Actually, it doesn't

Larger sprocket equals more chain speed. The length doesn't matter

@poplarmechanic is right. Bar length doesn’t matter for chain speed. It’s the amount of chain in the cut that counts. And chain speed is determined by the motor and sprocket pin count

@@therealzigzagman Fair enough, I was wrong in my thinking it seems.
